It was centered offshore, about 10 miles south of Malibu and 15 miles southwest of Santa Monica.
It was about 2 miles deep. It was centered 15.4 miles west of Venice and 16.3 miles west of El Segundo.
There were no initial reports of injuries or damage, according to the Los Angeles Fire Department.
The LAFD is now in earthquake mode. Crews will be conducting a strategic survey of all 106 neighborhoods and examining major areas of concern, including transportation infrastructures, large places of assemblages, apartment buildings, and power lines.
Earthquake mode, which is likely to take less than an hour, will complete once the survey is conducted from the ground, air and sea and consolidate reports.
